Across
- 5. the lithosphere is broken into moving pieces called
- 8. the thickest layer of the earth.
- 12. where plates move apart; also called seafloor spreading.
- 13. dense oceanic crust moves under less dense continental crust.
- 14. where plates slide past each other.
- 16. a combination of the crust and the uppermost mantle.
Down
- 1. land under the continents.
- 2. land under oceans.
- 3. type of crust that is thicker and less dense.
- 4. outermost layer of the earth.
- 6. where two plates collide.
- 7. innermost layer of the earth that is a solid metal ball.
- 9. a layer of the mantle that has convection currents of rock that move in circles like an escalator.
- 10. when plates collide and move up. Ex)Himalayas
- 11. type of crust that is thinner and more dense.
- 15. liquid layer of the earth made of melted rock.
